Lake Bomoseen Stormwater Study to Assess Sources of Sediment and Nutrients from Sucker Brook

The Poultney Mettowee Conservation District, in collaboration with the Lake Bomoseen Association (LBA), received a grant from the Vermont Department of Environmental Conservation’s Ecosystem Restoration Program to conduct a watershed assessment of the Sucker Brook sub-basin in order identify projects that will improve water quality in the lake.

As a result of Tropical Storm Irene, high levels of sediment built up at the mouth of Sucker Brook, near Crystal Beach.  Phosphorus binds to sediment and is carried to the lake from eroding gravel roads, streambank material, and other overland sources.  The Lake Bomoseen Water Quality Committee tracked the build-up of sediment in the years subsequent to Irene and estimated that 900 cubic yards of sediment has entered the lake through the brook since Tropical Storm Irene (this is equivalent about 60 dump truck loads).

Once these source areas are identified, projects will be designed to mitigate these inputs to the lake.  Other areas under study include some lakeshore properties and the State Park, which are suspected sources of sediment and phosphorus as well.  The study will focus on sources that are a direct result of storm events and floodwaters reaching the lake. As part of this project, the District, the towns of Castleton and Hubbardton, and the lake association will conduct a special meeting to discuss the results of the watershed assessment.  Please stay tuned for more exciting developments!

Contact info: Questions can be directed to Hilary Solomon, (802) 287-8339, or Terry Moran, the Lake Bomoseen Association Water Quality Committee Chair Person.  Any overland runoff that reaches the lake or areas of repeat local flooding are of interest to us!   Please contact Hilary if you can identify areas such as these!  Thank you!
